A key step in the development of a mining project is the successful delivery of the project Feasibility Study (FS). The FS should provide the project developers, stakeholders and potential investors the confidence that the project is technically, economically and sustainably viable and with a full understanding of the risk profile. Such information should enable all stakeholders to make an informed decision to support the project going forward.It is the authors experience that there are instances whereby a developer claims that a FS has been completed with a positive financial outcome, but at the implementation stage, if indeed it progresses to this stage, fails to deliver both on budget, schedule and/or performance. Such a scenario, which was common during the last commodity price boom, can leave investors confused and lead to volatility in the developers and JV partners share price.Over the last decade the share market and mining companies have recognised that greater transparency in disclosures, in the promotion of projects, is needed and justified if the mining industry is to compete for a justifiable proportion of investment funds available from the market.
